Latest Patents
One of Duane K Wise's latest patents is a method and apparatus for dynamic sound optimization. This invention comprises a system designed to compensate for the noise level inside a vehicle. It achieves this by measuring both the music level and the noise level through analog to digital conversion and adaptive digital filtering. The system includes a sensing microphone in the vehicle cabin to measure music and noise, preamplification and analog to digital (A/D) conversion of the microphone signal, and A/D conversion of a stereo music signal. Additionally, it utilizes a pair of filters that employ an adaptive algorithm, such as the Least Mean Squares ('LMS') method, to extract noise from the total cabin sound. The invention also estimates the masking effect of noise on music, adapts the music loudness, and optionally equalizes to overcome the masking effect. Finally, it includes digital to analog (D/A) conversion of the corrected music signal and transmits this signal to the audio system.
